You can get into weird cases with DWARF based unwinders when two paths through a function with different stack depths makes it impossible to reliably unwind.
LLVM has bugs in this regard with calls to variadic calls, since after a certain number of arguments have been passed in registers, you start pushing parameters on the stack (ABI dependant).
